To all 'wluim a may concern:

Be it known that I, SYDNEY B. Aus'rm, citizen of the United States, residing. at Pikesville, Maryland, have invented certaln new. and useful-Improvements in Recording and Adding Machines, of which the followa specification.

In is ily invention relates to adding and recording machines involving improvements on that type ofmachine disclosed in Letters Patent of the United States granted to G. Dudley, November 4, 1902,

One object of my invention-is to provide means whereby the adding mechanism may be combined with and attached to'a typewriter of ordinary form and of various makes now on the market A further object of my invention is to generally simplify the adding mechanism; ,provide means for insuring accuracy of operat-ion by preventing overthrow or underthrow of the parts; provide means for insuring certainty and accuracy of movement of the accumulator or transferring mechanism; provide simple and effective means for returning the number disks to zero, and to gensrally improve the construction and operation of the machineyas will be hereinafter described.

The invention consists in the features and combination and arrangement of parts referred to and particularly pointed out in the claims. r

In the drawings :-Figure 1 is a plan view of a machine embodying my invention with the recording mechanism and the accumu lator mechanism omitted; Fig. 2 is a front view of such machine; Fig. 3 is a side view looking from theright of Fig. 1 with the recording or t pewriting machine indicated generally in otted lines; Fig. 4 is a sec- 2 looking from the right; Fig. 5 is a detail sectional view along the selector shaft; Fig. 6 is a sectional view of the accumulator mechanism substantially on the line. 66 of Fig. 2; Fig. 7 is a view of a detail relating to the accumulator mechanism; Fig. 8 is a view ofa detail; Fig. 9 is a'detail view of a cam shaped arm operated by the key lever; Figs.

10 to- 13 inclusive are views of the carrying mechanism in different positions.

Adding mechanism.1 indicates the number wheels or'adding disks, each of which has a gear 2 which meshes with transmitting gears 3 on a shaft 4, supported in the frame 5 of the accumulator mechanism. These transmitting gears are engaged by toothed selectors preferably in the form of ,wheels 6, which, as a group, lie to one side of the transmitting gears, and disengaged therefrom when the machine is in normal condition ready for operation by pressing the keys. This relation of the parts is shown in Fig. 1.

The selectors are on shaft 7 supported in standards 8 and 9. As a group, they are adapted to move axially, for which purpose they are confined between brackets 10 of 9.

released from its escapement', by a coil spring 12 through the levers 13, 14, and link 15, as will be hereinafter'described. The selector shaft 7 is rotated to turn the group of selectors, through alps-corresponding in degree to the value of the adding keys operated, by an arm 16. fixed and 4, a curved link 17 and an arm 18 on a shaft 19 journaled in hearings in the frame, and operated each time one keys is operated, excepting the 0 key.

The rock shaft 7 has a spline bar 20 fixed thereto by arms 21, and the wide part 22 of this spline bar engages a notch of each se lector wheel, as shown in Figs. 4 and 7, so

position shown in Figs. 1, 2..and 6, all of them will be engaging the wide part of the spline bar, and upon the depression of any adding key the whole grou will rotate forwardly in the direction of t e arrow, Figs. 4 and 7, due to the, spline bar rotating with the rock shaft 7. The degreeof rotary movement corresponds to the value of the key 'operated, *for instance, the 1 key will rotate the selectors through an are equal to one tooth, the 2 key through an. are equal to two teeth, and so on up to and including the 9 key. The adding keys 23 are carried arms are of the same form, bfll'. they differ as to their respective locations on the transrack bar or carrier 11, which is driven, when thereon, Figs. 1

of the adding that, when the group of selectors are in the' by levers 24 pivoted at 25 to the frame, each having a pin 26 to operate, as the ke lever as a.

mitting shaft, and, consequently, as to their relation individually to the pins on the adding key' levers, so that different degrees of rotary movement will be imparted to said transmitting shaftand, therefore, to the selectors operated thereby.-

Each cam member or arm has a curved edge 27 to be borne upon by the pin on the key lever for turning the transmitting shaft, and each is provided with a locking portion consisting of a notch or recess 28 formed in the cam arm to receive the pin on the key lever immediately the cam arm has been turned through the predetermined arc corresponding to the value of the key operated.

Thjese notches or locking recesses are each struck on an arc the radius of which is the distance of the pin 26 from the pivot 25 of the key lever, so that when the pin, after operating" the cam arm, enters this locking notchor' recess, it will, by contact with the walls th'ereof,'hold the cam arm rigidly against further movement, and-thus hold the transmitting mechanism leading .to the selectors and the selectors themselves, against either overthrow or rebound, which would resultin underthrow; After entering this locking notch, however, thef'pin. together with the key lever, can continue its downward movement some distanc while holding the operating connections leading from" the shaft to the'selectors rigidly against overthrow or underthrow, so that this further movement of the key lever may, in proper order, perform the additional func tions dependent thereon, namely; the operation of the escapement mechanism of the selector carriage or rack bar and the release of the trip which controls the operation of the corresponding figure key of the typewriting or recording machine.

Escapement action of scZect0rs.The shifting movement of the selectors step by step along the shaft 7 and as a group, takes place as a result of the continued depres sion of the key levers, after they have turned forward the selectors, through arcs corresponding to the values of the keys operated, and is due to the contact of the key lever with a universal space bar 29 of a frame having its forwardly extending arms 30 pivoted to the frame at 31. T his frame has a rearwardly extending arm 32 connected by a link 33 and an arm 34 on the escapement rock shaft 35 Figs. 4 and 5 journaled in the frame at 36. This rock shaft carries two escapement dogs 37., 38, each pivoted to and preferably in a recess in the rock shaft, and both being under tension of a spring 39 connecting with their tail portions, the tendency of this springbeing to swing the upper or engaging end of the dog 37 to the light, Fig. 6, while the upper or engaging end'of the other dog 38 is pressed normally leftward. The dogs extend at d fferent angles in relation to the axis of the shaft, the dog 38 being normally in engagement with the rack bar 11 of the selector carriage, while the other dog 37 lies normally with Es'upper end to one side of the said rack air.

It will be understood that the selector carriage is under tension of the spring 12, exerted through the lever 14, constantly tending to force the carriage leftward, the carriage, however, being normally held against the tendency of this spring by the dog 38 which, itself, is held against swinging leftward by the wall of the recess in which it is located. Now, when a' key is depressed and the escapement rockshaft is turned forwardly, the dog 37 is carried into the wall of the recess at 40. At the same time, and upon the release of the dog 38 from the rack bar, it moves or swings toward the left under the action of the spring 39, and gets in position ready to en- 'gage the next teeth of the rack bar when the rock shaft turns back upon the release ofthe key, and when the key rises, the dog 38 will again engage the rack bar and hold the carriage when its full step movement is completed. By the operation ofthese dogs, the carriage is given a complete step" movement each time a numeral key is depressed. \Vhen, now, the selectors have been rotated forwardly through the proper angle, and have been accurately arrested and held by the locking notch 28 of the operating cam, and the key is continuing on its downward movement, the space frame will be depressed, and through theconnections the escapement rock shaft will be turned, thus giving a partial step movement to the select-or carriage, which movement is immediately completed on the release of the key. In this way, the whole group of selectors will be moved one step leftward from the position shown l'l Figs. 1 and 2, and the selector at the extreme left of the group will engage the first one of the transmitting gears 3, i. e., the one at the right of the group.

It will be seen from Fig. 6 that the selectors are loose on the shaft 7, and are free to shift along it. As a result of the shifting one step, just described, the selector at the left of the group has disengaged itself from the spline bar 20, which, it will be observed, is cut down or shouldered at 20, so that, when the selector has shifted t0 the left, past this shoulder, it no longer c nnected with the shaft so far as rotation is concerned, and, therefore, it will remain in its advanced or forward position to which it has been rotated even after the key is released, for it is now in engagementwith the guide bar 83 and with the transmitting gear 3 and there- 5 by with the number wheel corresponding thereto. On the release or rise of the key, however, allthe other selectors which lie to the right of the shoulder 20 and are, therefore, still engaging the spline bar, are rutated back to normal position by means of the spring 41 connected with the transmitting shaft 19. Y

I have now described how the selectors are moved forwardly, preferably rotatively, upon the depression of any of the keys from 1 to 9; how this rotary movement is accurately arrested as a result of depressing the keys; how the selector carriage or rack then shifts to the left as the key completes its full movement down and up so that the selector at the left of the group will'engage the first transmitting gear 3 leading to the adding wheels 1, and how, on the release of the key, all the selectors not engaging the transmitting gears are returned to normal positionwith the spline liar and shaft 7, leaving the engaged selector in advanced position, because, in engaging the transmitting gear 3, it has disengaged itself from the spline bar and, consequently, from the shaft 7 and the key so far as rotating movement is concerned. Supposing now another adding ke or,in fact, the same key,-is depresse a similar series of actions takes place, the remaining selectors of the group, that is, those excepting the ones engaging the transmitting ge rs, will be advanced and will shift another step to the left while held againstrotation by the bar 83, thus making 40 the previously advanced selector engage the second transmitting gear of the group and causing the second selector to engage the first transmitting gear, and upon release of the key these two selectors will remain in their advanced or forward position and in engagement with the two-transmitting gears, while all the other selectors will'rotate back to normal position. These actions are repeated until all the keys corresponding to 60 the digits of the number to be added are operated, and the selectors, have 'rotated through the different angles corresponding to the valfas ofthe keys depressed, and have gotten, into engagement with the transmitting gears, whereupon the machine is ready to be operated to transmit these "alues or register them on the adding disks. For this purpose it is simply necessary to rotate all advanced selectors back to normal osition, whereupon that selector which had een set or rotated forward, say, for instance, three teeth or spaces, and that which has been rotated or set in advance rotatively fiv spaces, and the one which has been set forward, say, seven spaces, owing to the dep'ressionof the 3, 5 and 7 keys, will, in returning to normal posit1on, rotate the transmitting gears 3 through angles corresponding respectively to the angles or degrees that the respective selectors have been advanced,

namely: one through the space of three teeth, the neiit through the'space of five teeth, and the other seven teeth, and this movement will be transmitted to the number disks and they will register the values of the operated keys; This return to normal position of the engaged selectors is due to the operation of the handle,42 at the right of the machine, the shaft-43 of which has a segment 44 meshing with a gear 45 fixed on the/rock shaft 46 journaled in the frame. This shaft has-a cam at? fixed thereon engaging a lever 48 pivoted to the frame at 49 and connected by a link 50 with a bail or frame 51 mounted to turn loosely on the 35 shaft 7 of the selectors' and carrying a 'selector returning bar '52 which passes through slots 53 in the selectors N ow, when the handle 42 is drawn forward, after more or less of the selectors have been 0 turned and set into engagement with the transmitting gear wheels 3, thereturn orpick-up bar 52, through the described connections,-will be moved in the arrow direction, Figs. 4 and-6, and, striking the end. 5 wall of the slot 53 of those selectors which have been advanced from normal position, will return these selectors to normal position, and in this movement the transmitting gears 3 will be turned to register the values on the number disks according to which keys have been operated.

'1 he above described movement of the selectors are substantially the same as those described in the patent, above referred to, the means for moving them and for arresting them to prevent overthrow or underthrow and for returning them to normal position, as well as the escapement mechanism being, however, improvements upon the \i n- 11o vention disclosed in saidpatent.

In addition to the movements imparted to the selectors by the operation of the handle, as above described,- the said handle, as in the patent .referred to, in the final part of its movement, returns the group of selectors to the right or to disengaged position in relation to the transmitting wheels 3. For this purpose a cam 54 Fig. 1 is fixed to the rock shaft 46 to turn the lever 13 to the right as the handle is completing its forward movement. and this, through the link'15 and the lever l t connected pivotally and directly to the rack or carriage of the selectors, will return the same to the right and withdraw all of the selectors from engagement with the transmitting gears, they then occupying the position at the right 'of the said transmitting gears as shown in Figs. 1 and 2.

When the lever 13 swings to the right. it 130 will place the spring 12 under full tension ready to move the selector carriage leftward step by step as the escapement mechanism is operated by "the keys. This spring, itwill be seen, instead of being secured to a fixed point'on the frame, is attached to the lever 14 nearer the pivot thereof than the point at which the other end of said spring is attached to lever 13 in relation to its pivot, and as a result of this the spring moves bodily in performing its function, at the same time contracting slightly as it imparts the step by step movementto the se lector carriage.

C'owectz'ng or eliminating mechanism.- This' mechanism relates to means for correcting or eliminating a mistake of the operator without transmitting the same to the accumulator or adding mechanism; that is to say, should the operator have struck the keysincorrectly and the selectors have become engaged with the transmitting gears. It.ispossib1e,.by my present improvement, to return the selectorsto their disengaged positionwithout transmitting their values to'the number wheels. For this purpose a pawl 54 having a tooth or pin 55 Figs. 5 and 8 normally disengaged from the rack of the selector carriage, being pivoted at 56 to a lever 57 pivoted toa post 58 of the frame and connected by a link 59 with an arm 60 on a rock shaft 61 mounted in a bracketBQ, and having another arm 63 connected to or engaged by a push rod 64 slidirig in suitable bearings in the frame. The pawl is under tension of a spring 65 attached to its tail piece and to the frame, and when the lever 57 is operated from the push rod the pawl 54 will be thrown into engagement with the tooth of.the.rack of the selector carriage, and will move the same to the right a distance equal to one-half of the regular step movement of the carriage, the action beinglimited in any suitable manner so that the selectors which were engaged with the transmitting gears 3, will occupy positions opposite the spaces between the said gears and then, by operating the handle 42, the selectors will be first rotated back to normal position by the pick-up or return bar without setting up or transferring the values to the number wheels, and then the continued movement of the handle 42 toward the front will return the whole group of selectors to disengaged position at the right. The spring pawl 54 is controlled in its position bya stop pin 6? on the lever 57. The employment of the spring .65 allows the rack to move over the pawl to the right should the pawl be held in engagement with the rack teeth bycontinued pressure of the hand on the push rod, even after the selec tors have been rotated back to normal position. It-will be observed that the employment of this correcting or eliminating del vice enables the operator, after he has caused the selectors to engage certain ofthe 'trans mitting .wheels,' to free the said selectors therefrom and to return them to normal position and to disengaged position without,

in any way, affecting the transmitting gears 3 or setting up the values on the number disks. It will be seen also that the special form of escapement which I employ lends itself to the use of the correcting device in that the escapement dog or pawl which normally engages the rack is free to tilt at all times, when the rack is moved to-the right.

Carrying mechanism for the accumu Zut0r.This, in the patent above referred to, included a pin marked 162, one on each number disk, which, when said disk has been rotated to the point where it is .to'carry its. value onto the disk of the next-higher order, pressed upon a lever and set the carr ing mechanism in such position as to enab c it to be operated by the appropriate one-of the pins 164 on a pin drum 165 ope'rated'by the hand lever corresponding to that herein marked 42. Instead of using these pins on the number wheels to set the carrying mechanisms ready for action, I employ a series of points or arms 66 which, instead of being located on the number disk which is of comparatively small diameter, I place on an intermediate gear 67 of larger diameter than the number disks, and these points project beyond the toothed periphery of'the said intermediate gears. I prefer to form these points or arms on plates 68 suitably secured to the intermediate gears by pins 69, though I do not wish to limit myself to this way of forming or fastening the points in place. \Vith the intermediate gears, pawls 70 cooperate, these being normally disengaged from the transmitting gears through which the carrying action is performed, as shown in Figs. 6 and 7. These pawls are carried by plates 71 loosely mounted ona pin 72 mounted in the accumulator frame plates. These plates or setting members for the carrying mechanisms have depending tail pieces 73 normally out of the path of movement of the said pins 164 on the pin drum 165, but arranged to be thrown into the path of their respective pins when the arms or points 66 on the carrying gears 67 strike the shoulders or lugs 7i on the setting plates or members.

Itwill be noticed that I employ three armsor points 66 on the carrying gears, these being located ten teeth apart so that one-third of a revolution of the carrying wheel represents one complete revolution of the number disk, and, as a carrying operation must be performed at each complete revolution of a number diskr, the points or arms (36 are properly disposed on the car rying gears so as to accomplish this result.

The carrying pawls '70 are mounted upon the setting plates 71 by pins and cam slots at 75, 76, and a cam slot at 77 engages the fixed pin 78 of the accumulator frame, this being fixed 1n "the side plates of said frame. Each pawl is under tension of a spring 79 connected to its tail portion and to a cross bar 80 fixed in the accumulator frame plates.

iug gear 67 corresponding thereto and'which meshes with the transmitting gear 3 will also be turned step by step, but its movement will be without effect until'the number disk is about to complete one revolution, when the arm or point 66 on the said carrying gear will contact with the setting plate or member 71 corresponding thereto while the same is in the full line position of Fig. 6 and the dotted line position of Fig. 7, and shown also in Fig. 10 and set the same with its tail in the path of movement of its pin 164 on the drum 165, as shown in dotted lines in Fig. 6, and in full lines in Fig. 11, and, at the same time, the normally dlsengaged pawl 70 corresponding to the number wheel of the next higher order, will be thrown into position opposite the proper tooth ready to engage with said tooth of its carrying gear, by the setting movement of the setting. plate or member, as shown in Fig. 11, and then when the pin drum is rotated in the direction of the arrow, the setting plate will be moved back from the dotted line position of Fig. 6 to normal position, and, at the same time, its

pawl Wlll engage and turn the carrying gear as shown in Figs. 12 and 13 so as to carry the units on to the tens number diskor wheel, and as soon as this is accomplished, the pawl will disengage itself from the carrying gear, this being due to the ac tion of the cam slots and pins, and the spring, and this disengagement takes lace at the proper moment so that there will be no danger of overthrow, the carrying gear being arrested in proper position by a detent 80, there being one for each carrying gear, these detents being pivoted to a cross pin or bar 81 of the frame and being under tension of spring, such as at 81.

Briefly stated, Figs. 10 to 13, inclusive,

show the sequence of'o erations of the car-' r 'ing' mechanism as fo lows: Fig. 10 shows the parts in normal position. Fig. 11 shows them set back ready to carry when actuated by the pin drum. Fig. 12 shows the first 'action under pressure of the pin drum, and, Fig. 18 the final position with the pawl locked in the tooth of the gear to prevent overthrow. When the pin passes the end of the pawl carrier, the pawl drops to the normal position.

A number of advantages accrue from the construction above described over the arrangement disclosed in the patent referred to, among which may be'mentioned: By dispensing with the carrying pins on the number disk marked 162 in said patent, which required in addition tothe space for the gears on the number disk the-space necessary for-the pins and levers 161 to work in, I am enabled to use number disks having wider peripheries without increasing the total width of the accumulator mechanism, and thus place numbers of larger size thereon and, consequently, more legible than was possible in the old arrangement. Again,"

by placing the setting arms or points 66 on the carrying gears instead of upon 'the number wheels, I can locate these points at a sufiicient distance from the center about which they revolve to get a good clearance between the end of the point or arm and the shoulder or lug on the setting arm after striking and setting the same, so that, on the return movement of the setting member, it will not strike the point 66 and turn it, together with the carrying gear and number disk, backward to 9 when it should be turned to zero. Briefly stated, the present arrangement enables the point or arm 66 to have an arc of movement sufiiciently long for the step movement of the carrying gear to make the point or arm perform its setting function on the setting plate 71, and then pass beyond the same a sufficient distance to insure a good clearance when the setting plate or member is moved back to normal position, and thus prevent the setting member or plate from striking the point 66 and turning the carrying gear back with it. The carrying pawls are always disengaged excepting when actually operated.

As in the patent above mentioned, the pin drum 165 is rotated through a clutch or pawl and ratchet mechanism indicated generally at 82, this being of substantially the same form as that illustrated in said patent, and needs no particular description'herein, sufiice it to say that this clutch transmits only the forward rotary movement of the rock shaft 46 to the pin drum, the backward movement of said shaft being without effect on the pin drum. Theforward rotation, or, in other words, effective movement of the pin drum takes place on the backward movement of the hand lever 42 to normal position.

I have materially simplified the mechanism for detaining and guiding the selectors, and for detaining the gear trains connected with the number wheels, except when they are to be turned. This mechanism inrock shaft 46. This eam is formed to give the necessary movements to the spline bar in releasing and reengaging the selectors at the proper times, for instance, as the hand lever I 42 is pulled forwardly, the splined bar is withdrawn from engagement with the selectors, so that these selectors which have been advanced may be free to be turned back to normalposition for setting up the numbers on the number disk, and as this movement is completed, the spline or guide bar is thrown again into engagement with the selectors to hold them against displacement and to form' a splineor guide to maintain the relation between the selectors while they are moved as a group to the right into engagement with the actuating spline bar 20 and to disengaged position in relation to the number disks and transmitting gears 3. The arms 84 also carry a detent bar 88 to engage the transmitting gears 3 to hold them in proper relation to each other readyfor action. The cam87 is'so formed that, as the handle 42 completes its forward movement, after shifting the selectors to the right, the detent bar 88 will be withdrawn from the transmitting gears 3, so that, as the hand lever is returned to its backward or normal position, the number wheels and their geartrains will be free to be turned for the carrying of the values from order to order, which action takes place as above described, from the backward movement of the handle 42 through the pin drum. As soon as this carrying movement is completed, the arms 84 are again moved by the cam 87 to throw the spline or detentbar 83 into engagement with the selectors, so that said selectors will be accurately guided when moved leftward out of engagement with their actuator spline 20, this insuring that the selectors will be guided into.engagement with the transmitting gears 3. The same movement of the aims 84 moves the detent bar 88 into engagement with the transmitting gears 3 immediately after the carrying operation has been performed, so as to hold the number wheels and their gear trains accurately in the-positions they have assumed in relation to each other. The cam 87, for the purposes above described, has peripheral cam portions 89, a grooved by-pass 90 and an automatically operating gate 91 pivoted to the main part of the cam for properly directing the roller or pin 92 on the end of the lever so as to perform the necessary movements.

In order to insure the full movement of the handle 42 when started on its movement were either forwardly or backwardly, a lever 93 is provided pivoted to the frame at 94 and bearing, with its cam portion 95, iip'dii a pin 97 on the segment 44:. This lever is under tension of a spring 90 and the cil'cct is to press down upon the pin 97 and compel the segment to complete its-nuovement' as soon as the pin 97 is carried by the movement of the hand lever across the vertical axial plane of the segment.

Menu-n3 for returning number disks to zero-This mechanism includes a bar 98 extending across the peripheries of the inter mediate or carrying gears 67 and carried by arms 99 pivoted to the accumulator frame at 100, so that said bar will describe 'arc the'radius of which is larger than and eccentric to the periphery of the carrying gears. The resetting bar is normally held tothe 'rear out of the way of th points 66; a suitable spring being employed for this purpose, but when the bar is moved forwardly by the handle 98 and crank 99*, Fig. 5, 'it will strike the points of all those number gear trains which are not in zero position, and,will move them to such position. It will be noticed that the carrying gears mesh directly with the transmitting gears 3 and that the pawlmechanism is associated directly with the carrying gears, so that, in.

this. respect also, I have simplified the accumulator mechanism, having dispensed with the set'of gears 153 disclosed in the said patent.

Recording mechanisrm -In providing this mechanism I have sought to adapt the machine for connection with any type bartypewriting machine ofstandard form inrwhich the keys are operated by striking them, and for this purpose I provide connections to be attached to the figure key levers of typewriters of ordinary form. Such a typewriter is indicated at 100, it being shown only in general outline as representative of any suitable form of typewriter to which connection may be made. The figure key levers of such a machine have depending slotted links 100 engaging pins 101 on levers or arms 102 ivoted to the frame, and under tension of springs 103, connected thereto and to the adding key levers. These arms or levers 102 are held up normally against the tension of said springs by trip levers 104 having notched upper ends, engaging pins on the levers 102. The trip levers are ivoted at 105 to the frame and 'under tension of springs 106 in the base frame. They have arms carrying adjustable contact screws 10? which, in the final part of the downward movementof the adding key lever, will be pressed upon thereby, and thus the trip lever will be operated to release the spring lever or arm 102, and the spring 103 then exerting its force, will pull down the said arm 102 and operate the link ently of the adding mechanism.

I do not wish to limit myself to the means shown, except where specifically claimed, for carrying out the principle of my invention, as various-changes can be made without departing from the spirit of my invention.

The springs 103 are stretched by the levers 24 when the adding keysare operated, and their full power is not co'nstant-ly exerted, but they come into play to their makimum. extent when the adding keys are pressed down.

It will be observed that the carrying points 66 move always in one direction, but

y the arrangement of the setting plates and their connection with the pawls by means of the slots 75 the pawls are set by a movement in a direction opposite to that of theca'rrying points so t at when the sttin plates are moved back tonormal position the pawls will give an advancing movement to the carrying gears.

I claim V 1. In combination in an adding machine, registering members, keys, pivoted key levers and connections between said key levers and registering members including a shaft, 0. series ofcam arms fixed atdilferent angles thereon, said cam arms having locking notches at the ends of the cams to hold the connections against overthrow, said-notches extending at an angle to the cam edges and being concentric with the pivots of the key levers, substantially as described.

2.
